CLUTCH Alfred A. Conway, Cincinnati, ohio. ApplicationFebruary 20, 1930. Serial No. 429,903 Claims. (o1. 192469) This invention relates to clutches of the charthe pressure plate 21, similarly to certain of the acter shown in the patent to Conway No. 1,745, friction discs, is splined to the -niember 10 so 079 of January 28, 1930. The invention relates to that the pressure plate 21 can not rotate indemeans for taking up wear between the various pendel'lfJlY 0f 'the member 10, altllellgh it heere- 5 friction elements of the clutch and although the ciprooatine motion along the member10.
